This only started recently, but when I 'left click' on a webpage link, many times I get the following menu to copy text. See screenshot. I have to click again and maybe it will open the page that I want. It is annoying and I am at a loss in how to stop this mouse behaviour. I am sure it is something simple to fix, but I don't know it. I am using Opera browser, but the problem occurs when accessing folders, files etc. I get the highlighted in blue, as if I am copying rather than trying to open a folder/file. Basically, when I left click on something...I don't want to copy. I probably haven't explained it very well.
